What are the physical phenomena in the Spring Festival?

The physical phenomena of the Spring Festival are as follows

1, the frozen meat taken out of the refrigerator emits white smoke, which is formed by water vapor in the air liquefying when it meets cold.

2, 2. Freezing fish with cold water is faster than hot water, and solidification is exothermic.

3. When fireworks are set off in the New Year, the sound heard nearby is louder than that heard far away, and the loudness is related to the distance from the sound source.

When a person wearing glasses enters a room from the outside, the lens becomes blurred and liquefied when it meets cold gas, which is also a physical phenomenon.

The morning of New Year's Day was awakened by the vibration noise, because the vibration of the alarm clock made a sound, which was introduced into people's ears through the medium. Solids, liquids and gases can carry sound. When I found that the alarm clock had stopped, there was still sound because the original sound continued to spread.
